ESPECIFICATION forming part of Letters Patent No. 350,529, dated October12, 1886,

Application filed August 14, 1886. Serial No 210.930. (No model.)

To all whom it may concern:

Be it known that LTHoMAs EDWARD CORK- HILL, J r., a citizen of theUnited States, residing at Mount Ayr, in the county of Ringgold. andState'of Iowa, have invented a new and useful Improvement inOar-Couplings, of which the following is a specification.

My invention relates to an iinprovementiu car-couplings; and it consistsin the peculiar construction and combination of devices,that will bemore fully set forth hereinafter, and particularly pointed out in theclaims.

In the drawings, Figure 1 is a vertical longitudinal sectional view of acar-coupling embodying my improvements. Fig. 2 is a top plan View of thesame.

A represents a portion of the car-body to which the coupler is attached.

13 represents the draw-head, which is secured on the under side ofthecar in the usual manner, and is provided at its front end with the usualmouth, 0, to receive the couplinglink D.

E represents a coupling-jaw, which is pivoted in the draw-head by thebolt F, and extends longitudinally in the draw-head for a suitabledistance, and is provided at its front end witha depending lip, G, whichextends to the bottom of the draw-head, and is arranged across theopening or mouth at the front end thereof. The front side of the lip isbeveled, so as to adapt the coupling-link, when it strikes against thelip on entering the draw-head to raise the free end of the jaw so as toclear the link and permit it to enter the draw-head, and the couplingjawis then forced downwardly to its initial position by a coiled spring, H,which bears upon the upper side of the coupling-jaw. A shoulder, I, isformed in the lower side of the draw-head at a suitable distance fromthe mouth, and the coupling-link strikes against the said shoulder whenit enters the draw-head.

K represents a transverse rock shaft,which is journaled in suitablebearings on the front side of the car. This rock-shaft is providedat'its center with a crank, L, and the said crank is connected to thecoupling-jaw by means of a rod or chain, M. The ends of therock-shaft'extend to the sides of the car, and are provided withcrank-arms N, to which links 0 are attached.

P represents a rod,which extends vertically on the front side of thecar, the upper end of the said rod extending to the top of the car, andthe lower end thereof being connected to the crank L. A ring or loop isformed in the upper end of the rod P, by means of which it may be drawnupwardly byaperson stationed on the top of the car, so as to partlyrotate the rock-shaft and cause the free end of the coupling-jaw to beraised, so as to disengage the link in order to uncouple the car. Thesame. result may be effected by a person standing on the ground 011either side of the car by means of the crankarms N. When thecoupling-jaw is raised so as to disengage the link, it may be maintainedin that position by engaging the links 0 with books or pins R,whichproject from the sides of the car.

When the coupling is secured in its elevated position, it will beunderstood that two cars provided with my form of coupling may cometogether without becoming coupled. When, however, the coupling-jaw is inits normal position, the cars will become auto matically coupled whenthey come together.

Having thus described my invention, I claim 1. In a car-coupling, thecombination of the draw-head having the shoulder I on its lower side ata distance from its mouth, and the jaw E, pivoted in the draw-head, andhaving a depending lip, G, at its free end, adapted to bear normally onthe lower side of the draw-head, the said lip being inclined on itsouter side, substantially as described.

2. In a car-coupling, the combination of the draw-head having'theshoulder I on its lower side, the jaw E, pivoted in the drawhead, andhaving the depending lip at its free end, the spring bearing downwardlyon the jaw, and the rock-shaft having the arm connected to the jaw,substantially as described.

In testimony thatI claim the foregoing as my own I have hereto aflixedmy signaturein presence of two witnesses. F

THOMAS EDWARD CORKHILL, JR.
